Fastening peg for engagement in holes in foundation plate and object has longitudinal slit to permit expansion of outside diameter when plugs are forced into tapered inside diameter

摘要

The hollow fastening peg (1) has a cylindrical outside diameter with a central waisted portion (4) and a male threaded portion (8). The bore through the peg has two gently tapered regions (2,2a) joined by a short parallel portion in the center. A longitudinal slit (3) runs the length of the peg, allowing it to be expanded by two conical plugs drawn together by a screw arrangement.
